IMPROVEMENT IN F-L|ERBEARINGS FOR SPINNING-MACHINES.

Specification forming part of Letters Patent No.

y which my invention maybe distinguishedfrom others of a similar class, together with such parts as I claim and `desire to secure by Let- This invention relates to certain improvements in that class of apparatus known as thros'tle` doubling and spinning machines,7 in which a positive motion is imparted to the bobbin, and a variable motion to the inverted hier, and it has for its object to maintain the' flier in a position concentric with the y spindle, and prevent undue pressure ofsaid iiier upon the spindle in any direction, and to better retain the oil against the action of centrifugal force, as more fully hereinafter specified.

To this end my invention consists in making the bearing-surfaces of the boss of the hier and the copping-rail conical or semicircnlar in cross-section, and interposing between the same a soft substance, such as flannel, on which the weight of the iiier and its boss rests, to give the friction for producing the necessary drag on the thread as it passes down from the rolls throughl the eye of the inverted hier to the bobbin, which is driven by the spindle.

In the drawings, Figure 1 represents a sectional view of my invention, in which the boss of the ier is formed with a conical bearing, and the copping-rail with a recessed conical seat for the same. Fig. 2 represents the same arrangement, with the cones of a sharper angle. Figs. 3 and 4 represent sectional views of a modification of my invention, in which the boss of the flier is provided with a recessed conical bearing, and the copping-frame with a conical seat, upon which said recessed bearing lits. Figs. 5 and 6 represent sectional views of a modification of my invention, showing the flier-boss, having a convex spherical bearing, and the seat B on the copping-rail, with a similarly-shaped p 203,424, dated May 7, 1878; application led January 16, 1878; patented in England March 12, 1877.

concave. Fig. 7 represents a similar view, showing the boss constructed with a concave spherical bearing, and the seat on the eopping` rail with a corresponding convex shape. Fig. 8 represents a modication of my invention, in which the boss of the ier is provided with an annular bearing-surface, conical in crosssection, and the vcopping-frame with a correspondingly-recessed seat; and- Figs.. 9 and 10 represent modifications, in which the annular bearings and seats are semicircular in crosssection.

The letter A represents the boss of flier, which is formed with a bearing-surface angular or semi-cylindrical in cross-section; and B, the seat on lthe copping-rail, which is correspondingly shaped for the reception of the bearing on the boss of the iiier. The letter G represents a packing of soft, porous material, such as flannel, or other analogous substance, interposed between the bearing and its seat.

The bearing on the boss of the iiier and its corresponding seat on the copping-rail may be formed as shown in any of the various modifications of my invention, although I prefer to make'the boss of the iiier with a convex bearing, and the seat of the same on the copping-rail in the shape of a concave recess, for the reason that the lubricating material will be better held in such construcsurface, in combination with a correspondinglyshaped seat on the copping-frame, and an interposed packing of soft or elastic material, substantially as and for the purposes specified.

In testimony wh ereof I have signed my name y to this specification in the presence of two subscribing witnesses this 17th day of December, 1877.
